Cannabis 101 —
Foundations of the Plant
Learn how cannabis interacts with the body, what cannabinoids and terpenes do, and how to confidently guide patients based on their needs.
Cannabis is a plant that contains active compounds called cannabinoids, which interact with the body's endocannabinoid system (ECS) to influence pain, sleep, appetite, mood, and more.
The two most well-known cannabinoids are:
- THC (tetrahydrocannabinol) — Intoxicating. Helps with pain, sleep, and appetite.
- CBD (cannabidiol) — Non-intoxicating. May help with anxiety, inflammation, and general wellness.
There are over 100 cannabinoids in the cannabis plant — each with its own unique effects. THC and CBD are just the starting point.
The ECS is a natural system in your body that helps maintain balance — also known as homeostasis. It affects mood, immune response, digestion, sleep, and more.
- Endocannabinoids — Chemicals made by your body (like anandamide)
- CB1 & CB2 Receptors — Located in the brain, nerves, organs, and immune cells
- Enzymes — Break down cannabinoids once they've done their job
When patients ask "how does cannabis work?" — the ECS is the answer. It's the lock-and-key system that makes it all possible.
Beyond THC and CBD, there are several cannabinoids gaining traction in medical cannabis:
- THC — Intoxicating; helps with pain, appetite, and sleep
- CBD — Non-intoxicating; calming, anti-inflammatory
- CBG — May support focus, gut health, and inflammation
- CBN — Associated with sleep and sedation
- CBC — May help boost mood and reduce pain
- THCV — Possible appetite suppression and energy boost
Cannabinoids and terpenes work better together than alone. This synergy is known as the entourage effect.
For example, CBD can reduce some side effects of THC, while certain terpenes may enhance pain relief or relaxation.
This is why full-spectrum products are often recommended over isolates — patients get the benefit of the whole plant working together.
Terpenes give cannabis its smell and may also affect how it feels. They work alongside cannabinoids to shape the overall experience.
- Myrcene — Sedating, relaxing (earthy, musky)
- Limonene — Uplifting, mood-boosting (citrusy)
- Linalool — Calming, soothing (floral, lavender)
- Pinene — Mental clarity, alertness (fresh, pine)
- Caryophyllene — Anti-inflammatory (spicy, peppery)
Pro tip: Encourage patients to smell products when possible. The aroma they're drawn to often aligns with what their body needs.
How a patient consumes cannabis changes how fast it works and how long it lasts. Here's a quick reference:
| Method | Onset | Duration | Best For |
|---|---|---|---|
| Inhalation (vape/smoke) | 1–5 min | 1–3 hrs | Quick relief (pain, anxiety) |
| Sublingual (tincture) | 15–45 min | 4–6 hrs | Daytime balance |
| Capsule | 30–90 min | 6–8 hrs | Sleep, sustained relief |
| Edible | 30–90 min | 6–8+ hrs | Appetite, overnight use |
| Topical | Local only | 2–4 hrs | Joint & muscle relief |
Golden rule: Start low and go slow.
- THC (oral) — 2.5–5 mg for beginners
- CBD — 10–25 mg is a common starting range
- Inhaled THC — 1 puff, then wait 10–15 minutes before more
Every person's tolerance is different. Let patients know it's okay to adjust over time — finding the right dose is a process, not a one-time decision.
As a budtender, you're a patient's first point of contact — not their doctor. Keep these principles in mind:
- Ask about goals — Sleep? Anxiety? Pain? Let the patient lead.
- Focus on effects, not diagnoses — Talk product types, not conditions.
- Use plain language — Skip the jargon. Be relatable.
- Know when to refer — If unsure, send them to a pharmacist or clinician.
The best budtenders don't have all the answers — they ask the right questions and know where to point patients when they need more help.
